This Jaeger LeCoultre Atmos Clock bellow can be used in nearly all of the Atmos Clock models made prior to the Atmos 540, or the 1990’s.
It has been recharged as of November 20222, and it did not have a specific leaking point. It has been tested and it functions properly. The Atmos Bellow you are purchasing is the unit photographed above and below.
Inside the Bellow it is inscribed with the date: March 21st, 1966, meaning that it likely came from an Atmos Clock Caliber 528-6. However, this Bellow can be used in nearly all of the Atmos Clocks produced before the Atmos 540 or the 1990’s.

This Atmos Clock is in original, good condition. It has some scuffs, minor scratches, and had a dedication plate removed from the back of the bottom base, leaving a bit of residue. The plate was thankfully on the backside of the base originally, so the front of the clock doesn’t show these marks. The front glass panel has chipped corners.
The clock has been serviced, and has been running great for several months. Despite a bit of external case wear, the clock is very nice. If interested, the case could be reconditioned some day. Also, a new dedication plate could be placed over the spot of the old one, either personalized for someone special, or a general style with the maker, model, serial, and date of manufacture.
Since this clock has some case wear and character, we are willing to sell it a reduced price. It is a great running and functioning clock, and makes a perfect model for an entry level collector’s item. We did our best to photograph the flaws and wear.

The Atmos Clock powers itself with the expansion and contraction of the bellow. This unit is contained inside of the round “drum” (photo below) on the backside of the clock. The entire configuration is called the “Motor,” a name which is befitting, because this is where the mechanical energy that the clock uses to run and keep time, is harnessed.
(Bellow Drum)
The Atmos Clock Bellow is constructed of stainless steel membranes, which are hermetically sealed and filled with a combination of liquid and gas that is responsive to minor changes in temperature and barometric pressure of the environment. These changes cause the bellow to expand and contract ever so slightly, pumping a ratchet system, and eventually winding the mainspring of the Atmos Clock (Learn more about how the Atmos Clock winding system works with the YouTube video at bottom of this page).
The Atmos Clock Bellow that has gone flat can either require a recharge/refill, this is where the bellow doesn’t have a leak but the chemical state of the gas inside of the canister has changed;
Or the Atmos Clock Bellow could need to be repaired and then recharged. This takes place when there is a hole or leaking point on the stainless steel membrane. It is patched/sealed and then the Bellow is recharged. After it is tested to make sure it will maintain it’s function.
You may send the Atmos Bellow for repair/recharge inside the motor drum if you wish, or else it can be shipped alone as well.
The Motor Drum is attached to most clocks with 8mm cap nuts, the other clocks feature a reverse bayonet fitting (Caliber 540 and above).
Price for Atmos Clock Bellow Repair is $150 & Return Shipping/Insurance is $20 USD(U.S. Clients only. For international shipping rates please contact Michael at curtsclocks@gmail.com before shipping).
Please include a check made out to Michael Holman for $170, along with the Atmos Bellow for repair.
This payment will compensate Michael for his time to do the bellow testing and attempted repair. Not all of the bellows are repairable. Occasionally the entire inside of the stainless steel membrane is compromised to a level beyond sealing a single leaking point. Also, if the membranes are leaking at the seam or joint, then it is very difficult to seal it back up properly.
Michael is able to repair quite a high percentage of the bellows, so please don’t be discouraged to hear that not all of them are repairable. In the event that your bellow cannot be repaired, your payment compensates Michael for his efforts. It is similar to the concept of a labor rate in an automotive garage.
If your bellow is beyond repair, there is a good chance that Michael has a replacement bellow for sale if you need to replace it.
Directions for Returning The Repaired Bellow to Motor Drum:
Place bellow in freezer until it shrinks completely flat (10 mins).
Quickly put the bellow in the Atmos drum.
Place coil spring in center of bellow unit, and connect within the drum cover.
Align screw posts on cover, diagonally, so that the Lecoultre name emblem located on the back of outer drum is aligned at the bottom and right side up.
Replace motor protector plate on complete motor, carefully pressing into place without bending.
Put motor onto clock and hold steady while tightening down 8mm caps, being careful not to over pump winding system.
WARNING:
Never allow a full bellow to over-expand at room temperature without bands restricting, the bellow can crack at side flexion points of membrane.
